Problems solved by technology

[0005] However, the folding bike of the above structure has the following disadvantages: (1) the double-fold folding structure makes the thickness of the vehicle body twice the original, so its thickness is relatively large; limited, even if the inner tube is shrunk into the outer tube, there is still a fixed basic height of the vehicle body. Therefore, the above two points bring inconvenience to the carrying and storage of the folding car; (2) the above-mentioned folding car needs to be provided with a special folding device and Only by locking the parts can the folded car be in a locked state for easy portability

Embodiment 1

[0049] See attached Figure 1-9 Shown, a kind of folding bicycle comprises front wheel, front fork 2, foldable handlebar 1, vehicle frame, rear wheel, rear fork 8 and front and rear sprocket wheel and chain 10, and described vehicle frame mainly consists of beam 6 and The middle tube 5 is composed of the seat tube 4 and the middle tube 5, and the rear fork 8 is hinged with the middle tube 5 through a rotating connection structure. The rear wheel is folded inward along the hinge axis and when it reaches the folded state, the clothes hanger 11 becomes a parking stand, and when the seat tube is inserted downward to reach the folded state, the lower part of the seat tube is offset against the rear wheel;

[0050] The positions corresponding to the front and rear sprockets are all equipped with an anti-off chain structure; when the foldable bicycle is in the unfolded state, the front upper part of the rear fork is against the vehicle frame.

[0051] In the above, the foldable hand...

Embodiment 2

[0061] See attached Figure 10-11 Shown, a kind of folding bicycle comprises front wheel, front fork 2, foldable handlebar 1, vehicle frame, rear wheel, rear fork 8, the battery and the control circuit that are located on the vehicle frame and are located on the axis 9 Pedals 14, drive motors are provided on the front or rear wheels, the frame is mainly composed of beams 6 and middle tubes 5; the seat tube 4 is connected with the middle tube 5 in a sleeve type, and the rear fork 8 is connected through rotation The structure is hinged with the middle tube 5, and its hinge axis is set parallel to the ground and located at the rear side of the middle tube 5, so that the rear wheel is folded inward along the hinge axis and when it reaches the folded state, the hanger 11 becomes a parking support, and the seat tube is inserted and contracted When the folded state is reached, the lower part of the seat tube is against the rear wheel;

[0062] When the foldable bicycle is unfolded, ...

Embodiment 3

[0069] A folding bicycle, including front wheels, front forks, foldable handlebars, frame, rear wheels, rear forks, front and rear sprockets and chains, the frame is mainly composed of beams and middle tubes; Tube-in-tube connection, the rear fork is hinged to the middle tube through a rotating connection structure, and its hinge axis is set parallel to the ground and located on the rear side of the middle tube, so that when the rear wheel is folded inward along the hinge axis to reach the folded state, the seat When the tube is inserted down to the folded state, the lower part of the seat tube is against the rear wheel;

[0070] The positions corresponding to the front and rear sprockets are all equipped with an anti-off chain structure; when the foldable bicycle is in the unfolded state, the front upper part of the rear fork is against the vehicle frame.

[0071] In the above, the foldable handlebar is an existing technology, and a handlebar quick release structure can be ad...

Abstract

The invention discloses a folding bicycle, comprising a front wheel, a front fork, a folding handlebar, a frame, a rear wheel, a rear fork, a front chain wheel, a rear chain wheel and a chain, wherein, the frame mainly comprises a crossbeam and a medium tube; a seat tube and the medium tube are in extension-type connection; the rear fork is hinged with the medium tube through a rotary connection structure; the hinged shaft of the rear fork is positioned between the medium tube and the rear wheel parallel to the ground; when the rear wheel is folded inwards along the hinged shaft to achieve a folding state, the seat tube is inserted downwards to the lower part of the seat tube at the position of contacting with the rear wheel; chain dropping resisting structures are respectively arranged on the positions corresponding to the front chain wheel and the rear chain wheel; and the front upper part of the rear fork is against the frame when the folding bicycle is in an unfolding state. The folding bicycle of the invention has smaller bicycle body when being folded, and is convenient for carrying and placing.

Description

technical field [0001] The invention relates to a folding vehicle, such as a folding bicycle or an electric vehicle. Background technique [0002] Folding bicycle is a convenient means of transportation, which has developed rapidly in recent years and is favored by more and more consumers. [0003] The main advantage of the folding bike is that the volume of the folding bike is reduced, which is convenient for carrying and storing, especially in some places that cannot be reached by buses and subways, such as in residential areas, after taking the bus or subway, use the folding bike that you carry with you as a means of transportation Tool, save time and effort, very convenient. [0004] Existing folding bikes are usually equipped with a folding structure similar to a sheet hinge in the middle of the frame beam, and the rotating shaft is set perpendicular to the ground. The length of the car body, while the handlebar and seat adopt a two-section sleeve shrinkage method to ...
